    Alpina B3S Biturbo replica airbox + inlet tubes - photos

    As I've mentioned in other threads, I have recently acquired a replica of the intake system that Alpina uses for their Alpina B3 S Biturbo, and which features aside from a carbon-look airbox - which is slightly larger than the stock 335i airbox and inside smoothened out with less edges - also the two inlet tubes that connect the airbox to the two turbos (the OEM part no. of the original 335i parts are 1371755654 and 13717556550). Alpina has widened these intake tubes as they are quite pancaked due to the restrained space in the engine bay, and have in particular made the inlet diameters larger. You can see it here:

    Unfortunately the original Alpina parts are not available as Alpina does not sell them to anyone not owning a B3 S Biturbo. As a consequence, they have been replicated by a shop specialised on manufacturing fiber-glass reinforced plastics called Gfk-Technik Glück: http://glück-gfk-technik.de/airbox-135i.html. They have taken the Alpina intake system, made the inlets even a bit wider, applied carbon for the lid of the airbox and used aluminium machined connectors.

    This shop usually does not retail this product but rather sells it to tuning shops such as Tuningwerk or Manhart, who then sell it on (for a substantial margin). The German tuner Motorsport24 for example sells the airbox for 2500 EUR (see here: http://www.motorsport24.de/motorspor...box::2027.html), Manhart for 2800 EUR. The manufacturer himself sells it for around 1800 EUR, which gives you an idea of the margin that some tuners obtain for themselves.

    Due to requests of some of you, I've made a few photos of the airbox which will be installed in my car in the course of next week. You will also see on the photos that you need two hump hoses and four clamps to attach them, in order to connect the upgraded inlet tubes to the stock intake system. In addition, I've made a photo showing the stock airbox besides the new one.

    Looking good, thanks for sharing. It seems to be quite an improvement over the stock airbox. Di you think it's a better solution than running DCI? And do you plan on measuring the performance, and if so how? You must have the most modded 335i in Europe by now, and most Alpina like by far Click here to enlarge

    Very nice @Alpina_B3_Lux. We're actually partnering up with a machine shop up here to look into making some parts soon too. Machine shop is owned by a family whose sons I'm very close friends with. Until yesterday I had no idea what capabilities they had and I was blown away. They have all the equipment and we're hoping to make a version of these pipes, although in some sort of metal (not plastic), and offer them to those interested. We're looking for other ideas and possibly also doing another catch can based on the knowledge gathered through my PCV research but we'll see. I'll post up some photos of the shop in another thread when I get a chance.

    Looking forward to seeing how those pipes feel to you on the car. Good luck!

    I wanted to do these pipes with my RBs forever. Really hoping I can get something going with this shop, pretty sure there will be good gains to be had at higher RPMs on RBs and higher boost.

    Yea....larger intake plumbing looks great. Air box is worthless.

    Looks good! Thanks A LOT for sharing!
    After this the last thing to check would be the air inlets at the kidney grilles and the narrow part just before the box. I believe the new air box comes with larger intake to the box, so the air entering at the kidney grilles is the only worry.

    That's a crazy pricetag!!! Wowza! Nice looking airbox but I'd go for a Dinan + pipes at that cost. Looking forward to what dzenno will come up with.

    In the first pic that is from the seller's web pages the tube outlet diameter is 74mm vs 60mm stock.

    Calculating the difference in the area I got >50% larger area with the +14mm diameter.

    Edit. I just realized the pic is showing the air box end... What is the diameter in the other end is a very good question.

    right, another member brought this up in a separate thread and now Rob has. i almost missed it myself as you did. obviously the 'hot side' of the pancake pipe has to be able to fit the inlet diameter of stock turbos otherwise it would not fit on the stock turbos.. lol, right?

    That's right, it tapers down to stock diameter.

    The box looks awesome in person and the build quality is top notch. But the price tag is really hefty. Especially considering how much work is required to install the rear tubing behind the engine.

    Yes, exactly. On the cold side the diameter can be different to the stock system, and that is why you need the hump hoses on that side.

    A friend of mine had this system installed a few weeks ago, a BMW dealership quoted him about 5h work for this. I assume though that my indy shop will need more time than that, but we'll see!

    Have you measured it as well as stock? How much were they?

    However, both ends seem to be have worked on. Neither looks stock.

    What mods does your friend have that already has the pipes installed? Does he have any dynos? Did he say they made a noticeable difference? Please take pics comparing the stock pipes to the alpina ones and if you could measure them to show how much wider/taller they are then stock that would be great!

    Please specifically measure the side in question, this is not the time to assume when the data is readily available. It very well could be opened up appropriately for bigger inducer turbos... But if it necks down just the same as OEM inducer total waste IMO. 1 post for the day.

    Opening up one end of the tube but leaving the bottleneck intact would be worthless and so disappointing Click here to enlarge . If this is the case, this would be a perfect time to make the bottleneck bigger by the OP himself. The diameter should be 0.3 inches larger than stock if I remember right.

    That's pretty $#@!ing lame.

    I'm glad somebody makes a knock off then.

    Any idea on the gains?

    The friend of mine who's already had it installed a few weeks ago unfortunately didn't go on a dyno before he had the intake installed. I didn't either because I'm still in the process of figuring out the ideal COBB map for my RB turbo powered car. I have done tons of logs though with the stock pipes, and will do more with the pipes installed which may give you an idea where improvements can be located. IMO the gains will be even higher for people with upgraded turbos, as it's in particular in that case that the engine needs more air.

    My garage called me yesterday and said that there are some complications - as the front tubing is larger than stock, my additional oil cooler from AR Design will have to come off, as the oil lines are in the way. As I still have an improved stock oil cooler with roughly double the capacity that should still be fine.

    Another problem was that apparently the end of the front tubing that goes into the turbo is just a little bit too short and does not slide 100% into the turbo connector (it's only on the first of 3 clicks apparently). I hope to receive some photos so that I know what it looks like, but my mechanic says that he believes this not to be a problem.

    And although this is OT - don't get me started on the clutch / flywheel. As you may have heard, I had a ClutchMasters FX300 with a new stock flywheel installed a few months back, and now it appears both the flywheel and the clutch are scorched / glazed over. As a consequence, not only do I need to install a new clutch (HPF Feramic stage 1) which I wanted to do anyway, but I also need a new flywheel. The strange thing is that the problems I experienced with the CM clutch were there from the start (strong juddering when going into first gear and reverse), which means that the damage to the flywheel / clutch was also there from the start (as I did a proper 1500km break in procedure myself). I have the suspicion that the guy who installed the CM clutch (who is different from the garage that is currently working on my car) stepped on it from the start (also because the RB turbos were installed at the same time) and damaged both parts. Quite annoying, and a couple hundred $$$ lost again.

    I thought, they would make those out from the stock units, but they are apparently not modifying the stockers since the sizes are not stock.

    The stock inlet tube diameter matches the size of the inducer. In the pic the inlet tube will attach to the turbo from the left. Since RB inducer is appr. 0.3 inches bigger in diameter compared to the stock turbo, it would be useful if your shop would enlarge that end by the appr. 0.3 inches for it to match the inducer diameter of RB turbos.
